A name scheme? It would perhaps help RP and such, all KNF must go KNF|Name.Name and GRN go GRN|Name.Name, not related at all to the official faction, just for uniformity and so you can use the group invite function /fi KNF| etc.
Also, having experienced many many big battles, coordination is key to all efforts, you can't have 50 people all shooting a single target, so seperating groups of people into wings is the way to go, going to need a lot of wing leaders for this, I assume.
